acting quality.
The Reverend Mother in the original acting had more fear in the scene , she was like One Flew Over a Cuckoos Nest nurse fletcher...the new one? way too soft, bleh, and new one box of pain thing? Didn't seem french actor acting in pain either. More like Spocks "pain"
look at the acting cast of the original....you had Das Boot captain . And the new one? Can't even recall the actor then you have guy from Stargate and GOT, sure he's got the big warrior thing going but not the acting to go with it. Dean Stockwell...Patrick Stewart...do I need to go on.
Literally Villeneuve he just got acting cast from TV series.
Cinematically Villeneuve version has better elements, thanks to CGI and bigger budget but it doesn't grab you. It also drags, it literally gives nothing new despite being 2x the run time.
